Be it known that I, EMANUEL HALPERN a resident of New York city, Bronx County, State vof New York, and a citizen ofthe United States of America, have invented certain new and useful Improvements 1n Voices for Dolls, of which the following isa specification.

This invention relates to sound producing devices, more especially for the so-called talking dolls, or dolls that say mama. One of the objects lof my invention is to improve the device that produces a blastof air which is `forced through a reed, means being em ployed to interrupt the blast to produce two Fig. 3 is a face view looking from they left 1n Fig. 1; f

Fig. 4 is a sectional view on line H inv Fig. 3;

Fig. 6 is an enlargedfragmentary sec'- tional view, the section being taken lon line 6-'6 in Fig. 5; and f l y Fig. 7 Ais a fragmentary sectional view taken on line 7-7, Fig. 6, looking in the direction of the arrow.

One of the objects' o f my invention'is lto produce an air blast producingfdevice `or' bellows that will produce a maximum blast of air with minimummovement on the part of the movable member of the bellows.

nature requiring but littleymovement to op# erate it. To this 4end I providea hollow wind chest 8 of triangular formation having hingedly connected theretoy at`9 aplate 10. The ends and sides of plate 10 are connected to the edges of the chest 8 vby a fabric cover' 11 arranged to fold into the. chest, the plate being of a size permitting the plate to be moved entirely into the chest to expel air..

therefrom, as. indicated in Fig. 5. When plate 10 is forced into the chest, it (the further Objectis to producea device ofthis plate) andthe fahne member' n will ex mae pel all of the airfrom` the chest, as they fabric member will beforced `substantially 0h against thevinnersurface of the sidesfand one end of chest l8, the plate `being forced j against the bottom 12 of the chest. The

plate 10 will be hingedly connectedtofthe ottom 12,y at`9, bythe fabric member 11; as saidconnectionis lexible,the` plate can' be swung out of or into'thechest 8. To

operate the plate 10, I; provide a weight 13 i i i which -is carried bythe plate. y The plate 10 is further provided with an air' vchamber' 14 Y having a cover 15 carrying a vtube. 16. During the operation of the device, the plate will swingout of the chest or into the chest.l

To produce sound, I provide'reedsl? and y 18, one at each'end of al tubular body 19, the

tubular body `being mountedz within `a pocket 201 formed in the weight.y 13;y The pocket 2O is' divided into` two smaller-non? communicating pocketsbya' partition` 21 which SUPPOITS theftubularbody 19. Th'y reed 18 projects intovair .chamber v14, while reed 17 is locatedjin compartment 22op`posite an opening 23 in .the-plate 10. The reed 18 in air chamber 14 is 'located opposite a bleed hole `24 `cooperating with a valve 25 arranged to closesame.,against` the passage `of air from bellows but to allowcutside air to be drawnin. 1 i" When'the device istipped slightly tothe i 'i 1, the weight will causefplate left in yFig 10 to fall outwardly-,thereby drawing air 1n through tube 16 and bleed-hole24 (which will be necessarily a smallstream) .to op-,-

eratereed 1T `which,-by the aid of means tov be. described vwill yproduce relatively lou7v tones resembling the word mama. `The air drawn `in through tube16 yand bleed-hole 24 will pass throughreed'glS operatinglit, and

into tubular m'ember'20, through the reedv 1.7, without operatiing the-,latter to yfill the bellowswithair. When the device is tipped.

tothe right agaimthe weight will "force plate'10 into-the chest, thereby 'forcinglthep air through opening 23 into tubular'member 19, thence out pastthe reed 18, causing same togive forth a loud tone, which byy the`v aid of the means to be described will be divided into twotones yresembling When lair is'l` forced out' ofy the bellows, valve 25 wil-l close opening 24 to prevent escapeof air therethrough. Y i

Bymeans of my improved construction,

I am able to produce a device of the char-` l` through thereed 1S, whereby loud tones willv result. y

To cont-rol the flowof air into and out of the bellows, provide a drum 29 having heads 30 and 31, each provided with an opening 32. Over opening 32 in head 3l l place a yieldable diaphragm 33 having an opening 34tand a similar diaphragm 33 over openinggl in head 30. To interrupt the flow of air l provide tube 16 with a valve or shutter 35. rlhe tube 16, and drum 29, is connected by a flexible apron or connection 36, to bridge the space betw'een the tube and drum tok confine the indrawn or outwardly forced` air in order that itwill pass through the drum 29. When air is forced out of the wind-chest. thro-ugh tube 16, it will pass-through. the drum 29. The valve or shutter will close the opening i 34; in diaphragm when t-he plate l0 moves `outwardly'as it pass'es therethrough, thereby interrupting the sound. vWhen valve or shutter passes through opening Sil-'in diaphragm 30 theA sound will again be interrupted. The two interruptions referred to will produce sounds simulating the word ma-ma. The drum 29 is in thisl instance carried by bracket 35 secured at one end to the' bottom 12 of the wind chest. rlhe drum, as will be obvious, will be fixed relative to the plate 10.

What I desire to secure by Letters Patent is v l. In a sound producing device,'a windchest having a bottom member, sides eXtend-,

ing upwardly and outwardly therefrom, an end .memberl also extending upwardly and outwardly, whereby the mouth of said chest will be of greater area than the bottom thereof,` a plate hingedly connected -to the bottom member at the end opposite to the4 aforesaid end wall, a flexible cover-connecting the plate and edges of the slanting sides and end wall and a. sound producing device associated with the chest, said plate being insertable into the chest to expel air therefrom. f

2; ln combination witha wind chest having aymovablemember to draw air into said chest and also to force air out of said chest, a weight carried by the movable member having a pocket, a hollow body within the pocket, a reed at each end of said body, and a partition to separate the pocket into non-- communicating compartments, one of said reeds being in one compartment and the other reed inthe other compartment, said chest having an opening for the passage of air into and out of'same. i

3. ln combination with a wind rhest having a movable member to .draw lair into-said chestk and valso to force air out of ,said chest, a weight carried ,by the movable member having a pocket, a hollow body. within the pocket, a reed at each end ofsaid body, a partition to separate the pocket .into noncommunicating compartments, one of said' reeds beingin one compartment and the other reed 1n the other compartment, said chest having an opening for the passage of` air into and out of same,y and means to` interrupt` the flow of air into and out of said ohest. y

4. ln combination with a wind-chest having a movable member, a reed Yassociatedwith the chest, a drum supported by the` wind-chest adjacent the movable? member,

each end of said drum being provided with" an ope-ning, means to convey air from the wind-chest to saiddrum, and a shutter-carried by the movable member of the windchest arranged to pass through said open-i ings to interrupt the sound produced bythe reed.

5. In combination with a wind-chest havwith the chest, a drum supported by. the

wind-chest adjacent the movable member,y

each vend of said drum being provided with an opening, a tube carried by thev movable member of the chest, a'llexible apron or covering connecting the tube and drum and said carrier having anopening, a flexible diaphragm over each of said openings, alsoy having an opening, means to convey vair from the wind-chest to the carrier, and a shutter carried by thev movable member of the bellows operable through the opening in each lof said diapihragms toQinterrupt sound produced by the reed..- y
